Where does this come from, and can I check it?

Distinct nerve endings register cold and warm thermal stimuli independently. The figure is taken from NIH, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.

Is this really a human body fact?

Yes. It sits on the Human Body shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.

What else can I read about it?

The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.

Mondo Knows Facts

Specialised thermoreceptors detect temperature changes in skin

Distinct nerve endings register cold and warm thermal stimuli independently

Free nerve endings in skin contain specialised ion channels tuned to distinct temperature ranges. Separate populations of cold receptors and heat receptors transmit electrical signals to the hypothalamus, triggering protective behavioural responses or thermoregulatory physiological reflexes.
